Definitions
- the invention relates to a modular Coriolis flowmeter for determining a process variable of a flowable medium.
- Coriolis flowmeters have at least one or more oscillatable measuring tubes, which can be caused to oscillate using a vibration exciter. These vibrations are transmitted over the length of the pipe and are influenced by the type of flowable medium in the measuring pipe and its flow rate.
- a vibration sensor or in particular two vibration sensors spaced apart from one another can record the varied vibrations in the form of one measurement signal or several measurement signals at another point on the measuring tube.
- An evaluation unit can then determine the mass flow, the viscosity and/or the density of the medium from the measurement signal(s).
- WO 2011/099989 A1 teaches a method for producing a monolithically designed measuring tube arrangement of a Coriolis flowmeter with curved measuring tubes, whereby the measuring tube body of the respective measuring tubes is first formed solidly from a polymer and the channel for guiding the flowable medium is then incorporated in an exciting manner becomes.
- WO 2011/099989 A1 - as well as US 10,209,113 B2 - teaches a connecting body which is designed to accommodate and support a replaceable measuring tube module, comprising thin-walled plastic tubes. The measuring tube module is attached to a carrier device equipped with the necessary exciters and sensors via the connecting body.
- Coriolis flowmeters are known from the prior art, in which the temperature sensor is attached to the measuring tube by, for example, a soldered connection.
- a solution is extremely disadvantageous for disposable applications, since in this case electrical contact of the temperature sensor with a measuring circuit must be ensured when arranging the measuring tube module in the receptacle.
- electrical contact of the temperature sensor with a measuring circuit must be ensured when arranging the measuring tube module in the receptacle.
- Optical temperature sensors are basically known.
- US 2017/0102257 A1 discloses the use of an optical temperature sensor in a conventional Coriolis flowmeter. The temperature sensor is arranged inside the housing and faces the measuring tube.
- the invention is based on the object of resolving the problems mentioned.
- the modular Coriolis flowmeter according to the invention for determining a process variable of a flowable medium comprises:
- a measuring tube in particular a metallic one, for guiding the medium
- a contactless temperature sensor which is arranged in the electronics chamber and oriented in such a way that when the measuring tube module is arranged in the carrier module, in particular in the receptacle, the temperature sensor is directed at a surface of the measuring tube module, in particular a measuring tube surface of the at least one measuring tube and one of the surface of the measuring tube module, in particular the measuring tube surface of the measuring tube, receives the light beam emitted through the opening,
- the protective glass has chalcogenides at least in sections.
- the two materials mentioned for the protective glass are particularly suitable for the use of infrared sensors, as they are particularly transparent to radiation with a wavelength between 8 and 12 pm.
- the component corresponds to the primary sensor component or the primary exciter component.
- the primary sensor component or the primary exciter component can each be a permanent magnet, in particular in conjunction with a permanent magnet holder, which is connected, in particular in a materially bonded manner, to the measuring tube.
- the electronic components 40 may include connectors, cables, printed circuit boards, amplifiers, electronic circuits with resistors, capacitors, diodes, transistors and coils, digital and/or analog circuits, and/or a programmable microprocessor, ie a processor designed as an integrated circuit.
- the electronic components 40 also include the operating circuit, control circuit, measuring circuit, evaluation circuit and/or display circuit.
- Fig. 1 b shows a measuring tube module 4 arranged in the receptacle 11.
- the connecting body 7 rests on the support surface 26.
- the measuring tubes 3a, 3b protrude into the receptacle 11 so that they can oscillate, without touching the carrier module wall 31.
- the connecting body 7 serves to form a connection with a connecting body (not shown), in particular a distributor piece, with which the measuring tube module 4 can be connected to a process line.
- the measuring tube module 4 shown is not fixed.
- the temperature sensor 12 has a, in particular anodized, aperture 37 for blocking out interference radiation, a lens and an SMD IR sensor.
- the aperture 37 is preferably designed as a black radiator (eg made of anodized aluminum) so that it does not throw any radiation onto the SMD IR sensor.
- the temperature sensor 12 is arranged on a circuit board in the embodiment shown.
- the aperture 37 has a minimum distance d aperture min from the measuring tube surface 34 of 1 mm, in particular 2 mm and preferably 4 mm.
- the aperture 37 has a maximum distance dßiende.max from the measuring tube surface 34 of 18 mm, in particular 12 mm and preferably 9 mm.
- the protective glass 33 has, at least in sections, zinc sulfide and/or chalcogenides.
- the protective glass is shaped, designed and arranged in the opening in such a way that cleaning agent does not penetrate into the electronics chamber 40 when cleaning the carrier module 10.
- the protective glass 33 has a first diameter d ⁇ in a first section and a second diameter d 2 in a second section.
- the first diameter d ⁇ is larger than the second diameter ⁇ and the first diameter d ⁇ is larger than a smallest diameter d oef of the opening 32.
- the protective glass 33 has a maximum extension d Limax of a maximum of 15 mm, in particular 10 mm, in the longitudinal direction and preferably 7 mm and a minimum extension d L min of at least 0.5 mm, in particular 1 mm and preferably 3 mm.
- the receptacle 11 and the measuring tube module 4 are designed such that a distance d protection between the measuring tube surface 34 and the protective glass 33 is less than 5 and greater than 0.5 mm, in particular less than 3 and greater than 0.7 mm and preferably less than 2 and is larger than 1 mm.
- the dimensions are chosen so that as little surrounding radiation as possible penetrates through the opening into the temperature sensor 12 and that, if possible, only the radiation emitted by the measuring tube 3a is recorded by the temperature sensor 12.
- the temperature sensor 12 is directed at different surfaces of the measuring tube module 4 or determines the medium temperature based on different radiating surfaces of the measuring tube module 4.
- the contactless temperature sensor 12 is oriented in such a way that it is directed towards the surface of the primary exciter component 23 - in this case the primary exciter component 23 is a permanent magnet which is attached to the measuring tube 3a - and one away from the surface emitted light beam (see arrow).
